Bringing partner/spouse dependant while on Descretionary leave

Hello all,
I'm currently on the first 30 months of my 120 months route to settlement descretionary leave. My FLR HRO application was granted on the basis of my business in the UK (Business conisdered as private life) . Technically the leave was granted as an alternative to leave under Tier 1 entrepreneur visa existed at the time because there were exceptional circumstances that prevented leave being granted under any of the points based routes

I'm now in a relationship with someone from my home country and I would like to bring her with me after marriage. Since I only qualify for ILR in the next 8 years, is there any other option available to bring her with me ? As I mentioned in the beginning my reason for leave outside rules was not because I cannot return to my home country, its purely based on my business in the UK

Neither of us require access to public funds as I can support her financially . We just want to live together and its harsh if we have to wait for another 8 years. It would be much appreciated if anyone could advise whether there are any possible options.
